BMW 13538616079 is a genuine high-pressure piezo fuel-injector reference associated with BMW N54 applications and later Index 12 injector production. Specialist BMW sources identify 13538616079 as the updated genuine injector for N54 and N63 engine applications. See the exact injector reference.
N54 owners continue to search for these injectors because genuine sets are expensive and the market contains used, rebuilt and questionable low-cost alternatives.

Why Index 12 injectors are expensive
The N54 direct-injection system uses specialized piezo injectors. BMW revised the injector family repeatedly, and later revisions became desirable replacements. Continued demand from 135i, 335i, 535i and other N54 owners keeps pressure on genuine supply.
Do not diagnose an injector from a misfire alone
A cylinder misfire can also involve a spark plug, ignition coil, high-pressure fuel system, boost leak, wiring problem or mechanical issue. Replacing six expensive injectors without diagnosis can be an extremely costly mistake.
Used Index 12 injectors
A visible Index 12 marking does not prove that a used injector is healthy. Ask for source mileage, test information where available and clear photographs of identification markings.
Counterfeit and questionable rebuilt units
Extremely low prices deserve caution. A seller should be able to explain whether an injector is new genuine, used genuine, tested used or rebuilt, and what warranty is provided.
Coding and installation
N54 injector installation involves more than bolting the part into the cylinder head. Injector calibration information and the correct sealing/decoupling components must be handled using the correct BMW-specific procedure.

Frequently Asked Questions
Is BMW 13538616079 an Index 12 injector?
It is a key genuine BMW reference associated with the later updated injector design commonly sold as Index 12. Verify the marking and current supersession when purchasing.
Does it fit the N54?
Yes, specialist BMW application data lists numerous N54 vehicles. Final fitment should still be checked by VIN.
Does the N54 use six injectors?
Yes. The N54 is an inline-six and uses one direct injector per cylinder.
Do injectors need calibration coding after installation?
The injector calibration values must be handled according to the BMW service procedure for the application.
Can a bad ignition coil look like a failed injector?
Yes. That is why cylinder-specific diagnosis should happen before purchasing injectors.
Are used Index 12 injectors safe?
They can be usable, but revision marking alone does not prove flow, sealing or electrical condition.
Can different injector revisions simply be mixed?
Do not rely on a generic internet rule. Follow BMW application and service information for the exact vehicle and existing injector configuration.
